electrophysiology study

Abbreviation: EPS
A procedure used to determine the cause of life-threatening cardiac arrhythmias and the effect of treatments to prevent them. EPS is used typically after an episode of sudden death caused by ventricular tachycardia or ventricular fibrillation, or after symptomatic arrhythmias other than ventricular tachycardia or fibrillation, or in patients at high risk of death from these arrhythmias. Electrodes are placed within the heart and used to stimulate rhythm disturbances; the response of the heart can be studied after administration of antiarrhythmic drug therapy or under other controlled conditions.

Zipes: MADIT I was the first prophylactic ICD trial in which they took a group of patients, post-myocardial infarction, who had ejection fractions equal to or less than 35 percent and were subjected to an electrophysiology study with VT (ventricular tachycardia) induction that was not then suppressed by an anti-arrhythmic agent.
Both observers were blinded to the patient's name and accessory pathway location determined by electrophysiology study.
However, doctors say they can't carry out the 'urgent electrophysiology study and ablation' as long as the family doesn't guarantee the Dh40,000 bill.
